Get feature attribute when field name prefixed by table and database name?

Question

I have a polygon layer where one polygon matches multiple records in a table. I use JoinDataSource() to join these two items so I can set the definition expression of the polygon layer based on a field in the table. When I go to set the popup content for this polygon feature I need to query the records in the table that are related with the polygon layer. To use a relationship query, you need the objectId of the polygon, but I can't get that using feature.attributes.fieldName because the field name itself has a bunch of periods in it due to the database and tables names being prefixed on it. Using something like this won't work because javascript misinterprets the periods: feature.attributes.HabitatManagement.DBO.MgmtTracts.OBJECTID‍ How do I get around this? Here is the relationship query code: function mgmtPopupContent(feature) { var OID = feature.attributes.HabitatManagement.DBO.MgmtTracts.OBJECTID; var relatedQuery = new RelationshipQuery(); relatedQuery.outFields = ["*"]; relatedQuery.relationshipId = 0; relatedQuery.objectIds = OID; hbMgmtTractFL.queryRelatedFeatures(relatedQuery, function(relatedRecords) { //set popup content } }‍‍‍‍‍‍‍‍‍‍

Since feature.attributes returns an object, I just resolved to indexing into it using the full field name as the key. Note, I had to query the related records on the non-joined feature layer, I cannot query related records of a dynamic layer. function mgmtPopupContent(feature) { for (var attrb in feature.attributes) { if (attrb == "HabitatManagement.DBO.MgmtTracts.OBJECTID") { var OID = feature.attributes[attrb]; console.log(OID); } } var relatedQuery = new RelationshipQuery(); relatedQuery.outFields = ["*"]; relatedQuery.relationshipId = 0; relatedQuery.objectIds = [OID]; noJoinMgmtTractFL.queryRelatedFeatures(relatedQuery, function (relatedRecords) { console.log(relatedRecords); }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
